PATENT B U R N E R SPECIFICATION forming part of Letters Patent No. 623,386, dated April 18, 1899.

Application filed January 18, 1899. Serial No. 702,576. (No model.)

To'aZZ whom it may concern:

Be it known that I, HARPER F. SMITH, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Burners, which improvement is fullyset forth in the following specification and accompanying drawings.

My invention relates to that class of burners which are especially adapted for theburning of gas generated from gasolene or other hydrocarbon; and it consists more especially of the novel means for more effectually accomplishing the volatilization of the gasolene than heretofore, provision being also made by the employment of suitable air-intakes for augmenting the supply of oxygen to the burner.

It also consists in the provision of a vaporizing-chamber which is heated by the flames impinging directly thereon from the expansion-chamber or head of the burner, said flames acting upon an inclined face of said superheater.

It also consists in the provision of auxiliary superheating-wings which serve to hold the flames against the adjacent vaporizing-chamber, whereby the vaporizing effectis increased to a high degree.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a front elevation of a burner embodying my invention. Fig. 2 represents a vertical partial sectional View of the same. Fig. 3 represents a perspective view of the head of the burner and the superheater therefor modified somewhat from those shown in other figures. Fig. 4E represents a side elevation of the burner, showing the same with the air-intake pipes omitted. Fig. 5 represents a vertical sectional view of Fig. 4. Fig. 6 represents a side elevation of the upper portion of a burner and its adjuncts, showing the projecting wings whereby the action of the gas-generator is augmented to a high degree. Fig. 7 represents a section on line m, Fig. 6. Fig. 8 represents a section on line 3 3 Fig. 6. I

Similar letters of reference indicate corresponding parts in the figures.

above which is suspended a mantle J by any suitable means.

K designates a series of ports which are located in the wall of the expansion-chamber G on the side nearest to the generator 0, it being noted that the latter has on its juxtaposed upper surface an oblique wall L, inclined so as to receive the full impact of the flames from said ports, whereby the heating effect thereof is communicated directly to the generator or vaporizing-chamber O.

M designates a cup or pan for the reception of the hydrocarbon employed for startmg. i

In the construction seen in Figs. 1, 2, and 6 to 8, inclusive, the structure of the burner is substantially the same as already described, with the exception of the air-intakes for increasing the supply of oxygen and the auxiliary projecting wings, which serve to confine the flames and hot gases more closely in proximity to the generator, the structure of the above being now described in detail.

The mixing-tube F at suitable points is provided with the air-intakes N, the relative position of which will be understood from Figs. 1 and 2, said intakes having their largest diameter at their lowest portion and being contracted at the point P, where they discharge into said mixing-tube, whereby it will be seen that the supply of oxygen at the point where it is most essential is greatly augmented.

Q designates auxiliary heating-wings which project from the expansion-chamber G .toward the generator or superheater C, whereby auxiliary heating-chambers R are formed intermediate said wings and generator, said expansion-chamber being provided with a series of ports S adjacent said wings, by means of which the flames or highly-heated gases are enabled to play along the sides as well as the top of the generator, whereby the latter will be heated to a veryhigh degree,it being apparent that byhaving the chambers R open at top and bottom a free and unimpeded circulation is attained.

The operation is as follows: A small quantity of inflammable material having been placed in the cup M and ignited, the gasolene is introduced into the pipe B and is heated in the generator from ports K and S. The vapor then passes through the passage D and enters the valve-chamber E, from whence a jet of hydrocarbon vapor is projected upward into the mixing-tube or gas-chamber F, at which point it commingles with the oxygen, which is drawn in at the lower portion of said tube. The expansion-chamber G, communicating with and being directly above the chamber F, permits the air and vapor introduced to fully expand before passing through the screen or gauze II, where combustion takes place. A portion of the gas being permitted to pass from the expansionchamber G through the ports K and S, the flames caused by such deflection impinge upon the oblique wall L and sides of the generator O, which soon becomes heated to an intense degree and vaporize or volatilize the hydrocarbon, which after entering the pipe B passes through said generator 0, it being also apparent that by reason of the propinquity of the mantle J to the inclined face L the latter and also the rest of the top of the generator 0 become highly heated, said generator being further heated by means of the hot expansion-chamber G.

In the burner seen in Figs. 1, 2, and 6 to 8, inclusive, I utilize the same general principle hereinabove described, but employ in addition auxiliary heating means for the generator O and also increase the supply of oxygen in the mixing-tube.

It will be apparent that by the provision of the side wings Q and the ports S intermediate said wings and the sides of the generator C the latter is heated at its top and sides in the manner described and a free and unimpeded circulation of air around the generator is attained. By this means the hydrocarbon is much more effectively vaporized, and by the provision of the air-intakes N the supply of oxygen is also greatly increased, the effect of which is to make a fierce blue flame of great heat intensity and power. The burner operates effectively with or without .the intakes N and the side heating-wings Q, and in practice I prefer to cast the body of the burner,which contains the mixing-tube F, the

generator 0, the passage D, and its adjuncts,

integral; but the above parts can of course be cast separately and assembled afterward without departing from the spirit of my invention.

In practice I drill out the angular portions of the passage D and provide the plugs D and D which can be readily removed for the purpose of inspection or cleaning.

It will be evident that various changes may be made in the art which may come within the scope of my invention, and I do not therefore desire to be limited in every instance to the exact construction I have herein shown and described. Having thus described by invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a burner, a gas-chamber, a generator connected therewith, and a wing projecting from said chamber, the latter having a gasoutlet above said generator and a gas-outlet between said generator and wing.

2. In a burner, a mixing-tube, a generator adjacent thereto for the reception of the hydrocarbon, an expansion-chamber, said generator having an inclined upper wall below the upper end of the expansion-chamber and ports in the upper portion of said expansion chamber and located near the lower portion of said wall and adapted to discharge flames thereupon, in combination with air-intakes leading into said mixing-tube.

3. In a burner, a mixing-tube, an expansion-chamber or head supported thereon, a generator adjacent to said mixing-tube and head and having an inclined upper wall, ports in said head adapted to discharge flames on said wall, auxiliary heating-wings extending from said head toward said generator and portsin said expansion-chamber or head upon opposite sides of the generator adjacent to said wings.

4. In a burner, the combination of a mixing-chamber, an expansion-chamber,'a generator, a passage leading therefrom, said generator having an upper inclined wall, ports leading through said expansion-chamber and discharging upon said wall, auxiliary wings extending from said chambertoward said generator and ports located within said wings, whereby the sides as well'as the top of said generator are heated to a high degree.

5. In a burner, a mixing tube or chamber, an expansion-chamber, a generator adjacent thereto, a valved conduit leading from said generator to the lower portion of said mixingtube, air-intakes attached to the latter exterior thereof, said intakes having larger diameters at their lower portion and diverging from the top downwardly, said generator having an inclined wall, ports in said expansionchamber, for discharging flames upon said wall and openings in said chamber intermediate said wings and generator, whereby the sides of the latter are also heated.

6. In a burner, a gas-generator having ports leading from an expanding gas-chamber and impinging directly on the sides and oblique wall of a superheater and vaporizer, wings extending parallel with said generator, and between which and the generator the side openings are disposed side air-intakes, a mixingshoulder in said expansion-chamber, and a' gauze or screen resting on said shoulder.

8. In a burner, a gas-generator having side wings, side air-intakes, an expansion-chamber provided With ports therein, disposed in series above and upon opposite sides of the generator, a pin-valve controlling the action of the same a mixing-tube and a valve intermediate of said generator and mixing-tube.

9. In a burner, a gas-chamber and a generator connected therewith and projecting therefrom, the Wall of said chamber having gas-outlets therein disposed in different planes around the adjacent end of said generator, whereby flames are caused to impinge upon the adjacent surface of said generator.
